Persistent pupillary membrane in a feline: Case report

Abstract

The persistent pupillary membrane (PPM) is a rare congenital disorder, characterized by thin bands that cross the iris and usually does not affect the visual ability. This disease does not necessarily need therapeutic intervention, however, the place of attachment of this membrane can generate corneal or cataract opacity. The etiology has not been well elucidated; however, it is believed to have a hereditary background and this disease has already been reported in humans, dogs, rats, and felines. A feline, female, unsterilized, crossbreed, 2 years old, weighing 3.2 kg, was referred for preoperative evaluation of elective ovariohysterectomy, in which the left unilateral ocular alteration was observed, compatible with persistent pupillary membrane. The objective of this study was to present a case of PPM in a feline, a species with a rare incidence of this anomaly, making the case relevant for a better understanding of the epidemiology of this condition. As much as the disease does not have significant ocular repercussions, medical follow-up is recommended.
